I'm not sure calling with any 2 is the proper move even at 8:1 stack advantage IF the blinds are small (relative to the small stack). The only way he can come back is if he doubles up 3 times - by calling with crap, you make that much more likely.

I'mnot saying you should wait for an ace... but may as well wait until you have an above average hand (like Q7o or something). I think the break even point is when the SB+BB = remainder of small stack - then you should call with any 2.

So, like 500/1000 blinds short stack has 2000 you have 16000 before posting.
After posting: SS 1500 Pot 1500 You 15000 - trivial call with any 2.
But if it's like 50/100,
SS 1950 Pot 150 You 15900 - this is a bad call (with like 2/3o) if SS/SB pushes.

Unless you have a hot date or something - then just try to end it quickly
